A planar dielectric line having a first slot sandwiched between first and second electrodes is provided on a surface of a dielectric substrate. During manufacture an insert of a cushioning substance, preferably a piece of foam, is located between the inner sheet of material and the underwire. The pipe 3 is inserted into a retaining section 6 of the pipe holder 5 that is configured in such a manner that it locally surrounds the outer circumference 8 of the pipe 3 at least in part and with little play so that the pipe 3 can expand in the axial direction during casting but is secured against displacements in radial directions caused by buoyancy forces of the liquid casting material. A variety of cross sections including circular and rectangular are provided for the s-shaped duct. A tile table is provided that includes a flag that can be set for each tile that is compressed. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data.
